Relevance.The widespread introduction of digitalization and automation and their use in camera work leads to the acceleration of not only the labor process, but also the entire life of the labor subject. The effect of time perception on work was studied. However, the role of the subjective reflection of time intervals in an integrated system of labor activity in the conditions of work with time limits and deficits has not been studied enough.

Objective. Identification of the role and place of subjective assessment of professionally important time intervals in the system of regulation of activity in solving labor problems at different stages of the dynamics of the operator's performance in the production process.

Methods and sampling. Occupational study of labor; procedure for measuring time intervals; complex express methods for diagnosing the functional state of the subject of labor: 1) labor productivity, 2) physiological indicators, 3) subjective assessment of emotional tension (Spielberger — Hanin scale situational anxiety). The study involved female operators of the precision manufacturing “Assembly of Chips” of the electronics industry (21 people).

Results. The structure of the subjective assessment of the perception of professionally important time intervals determines the dynamic processes of time regulation. The temporal regulation of the labor of operators has specificity in different functional states arising at different stages of working capacity.

Conclusion. The time regulation of the main labor operations is central to the functional system of performing activities.
